Snom did make available IPv6 firmware, but this was buggy and no longer available, and Snom say that IPv6 will not be supported on the 3xx range.
Directory Name not being shown? A couple of times we've noticed that the Directory does not display the Name when that number calls in. Try turning off 'prioritise pbx number lookup' - This setting is found on the Snom web pages under Advanced - Behaviour. This setting means the phone will use the Name in the Directory rather than the Name given in the SIP messages when the call is sent to the phone.

You will also want to set up firewall rules, as per the VoIP Firewall page.
